ireport 4.5.1 通过java生成pdf的问题

wj63558595 2012-06-13 07:58:53



public static void main(String[] args) {

		DbUtilsTemplate db = new DbUtilsTemplate();

		JasperPrint print = null;

		try {



			InputStream is = new FileInputStream("F:/test2.jasper");

			JasperReport jasperReport = (JasperReport) JRLoader.loadObject(is);

			Map map = new HashMap();

			List<BookBean> list = new ArrayList<BookBean>();

			list.add(new BookBean());

			print = JasperFillManager.fillReport(jasperReport, map,

					new JRBeanCollectionDataSource(list));

			Date now = new Date();

			String fileName = now.getTime() + "";

			String filePath = "F:/iReport/" + fileName + ".pdf";

			// JasperViewer.viewReport(print, false);

			JasperExportManager.exportReportToPdfFile(print, filePath);



		} catch (Exception e) {

			e.printStackTrace();

		}

	}

我的test2.jasper没有定义任何变量属性。直接是一个空的模板。运行之后报错如下：
应该不存在版本问题。
